| This device was simply a gas grill igniter with finger grips added, sold as a pain-reliever. |
| It was actuated by stepping on it or by tripping a wire along the ground that released a flintlock igniter to fire the main charge. |
| The instructor pulled out a spark-striker that looked like any propane igniter, leapt up on the edge of the basket and relit the flame. |
| An igniter was inserted into the cylinder, heated to red-hot temperatures by supplying current. |
| When ignited by the primer, the igniter sends hot flaming gases around the charge to ignite the propellant. |
| The cases are cleaned, inspected and reassembled for propellant casting, and a new nozzle and igniter are installed. |
